It's hard to believe it's been 30 years since engineers at BMW dropped the much-revered M1's inline-6 into a 5 Series sedan, effectively creating a high-performance executive car. Time may have been cruel to us (The fat! The wrinkles!) but the M5 has aged well over the decades, and now BMW is commemorating the vehicle's big three-oh with a special edition.

The 2015 30th Anniversary Edition BMW M5 will be produced in a limited run of 300 units worldwide, with only 30 coming to the good ol' US of A. It will be the most powerful BMW production model ever, too, producing a whopping 600hp and 516 lb-ft of torque from its 4.4L TwinPower turbo V8, adding to the exclusivity.

With those numbers, the 30th Anniversary BMW M5 can run 0 to 60mph in roughly 3.7 seconds. Highway onramps take on a whole new element of fun in this M.

Other performance upgrades include a dedicated control module for the Active M Differential and an improved M-specific Servotronic function, as well as an improved M Dynamic mode, to make sure all that power gets to the ground. Unique styling and interior details consist of a Frozen Dark Silver Metallic exterior, 20 inch, bi-color M light-alloy wheels, and more "30 Jahre M5" (German for 30 years of the M5) badges than you can shake a stick at - on the kidney grill surrounds, the front fenders, door handles and twin dual exhaust pipes. The badge is also featured throughout the Alcantara-festooned interior, with a 1/300 identification number integrated into the Aluminum Trace trim strip on the front passenger side of the cockpit.

Predictably the most formidable M5 yet comes with an equally buff price tag, starting at $138,275. The 30th Anniversary Edition BMW M5 will be offered to the first 29 customers who reserve it by dialing the dedicated BMW Customer Relations hotline at 1:00pm EDT (10:00am PDT), on Wednesday, May 21, 2014. The catch? The phone number for the hotline will be revealed on BMW of North America's Instagram channel (@BMWUSA) over the five days leading up to May 21, beginning on Saturday, May 17. Each day, in addition to revealing portions of the call-in number, will offer fun facts about each of the successive five generations of BMW M5.

The final come up for purchasers of a 30th Anniversary Edition BMW M5 is an invitation to a one-day M Driving School at The Thermal Club, a private motorsports facility in Palm Springs, CA. The event will be held in the Fall of 2014 with more details to come.
